Tyra Banks may have gone from model to reality TV mogul, but she isn't quite where she wants to be.

"I wish I was more of a diva," Tyra told Tuesday's "Nightline" while talking about cast changes on "America's Next Top Model." "I wish [I] was harder, I wish I didn't care so much about being the nice girl all the time. Because a lot of the time people can take kindness for weakness … so I wish I had a little bit more 'oomph' in me."

"Sooner than later, definitely," Tyra said. "I have a lot of success and make a good living, but after a while you start going why?… I need to be able to share it with a family, and go to Toys R Us and buy a lot of toys for my child, you know what I'm saying? Like what is the point?"

But as for wedding bells, that's not something the superstar said she needs to hear.

"I don't have that 'Oh my god, I gotta get married!' thing," Tyra said. "If it happens, it happens, but it's never been like 'Oooo, I need to do that!' I don't know, it's a little difficult for me to understand, actually, when women really want to get married… I think it's because I'm a product of divorce, my parents divorced, so I don't understand that whole married thing when 70 percent of marriages fail and 50 percent of second marriages fail."
